Posted by mathbro on August 20, 2008
How to find the LCM (Least common multiple) -
Step1 : Factorize all the numbers into their prime factor.
Step2 : Collect all the distinct factors.
Step3 : Raise each factor to its maximum available power and multiply.
Example Find LCM of 10,20,25
Step1 :
10 = 2^1 * 5^1
20 = 2^2 * 5^1
25 = 5^2
Step2 :
2,5
Step3:
2^2 * 5^2 = 100
The biggest advantage of using this method lies in the fact that we can find out the LCM of any number of numbers in a straight line without using the conventional method.
